// This is a neat way of dealing with the (unusual) detached-signature case
// without disturbing things unduly. Consider DetachedDiskRep to be closely
// married to SecStaticCode; it's unlikely to work right if you use it elsewhere.
//
// Note that there's no *writing* code here. Writing detached signatures is handled
// specially in the signing code.
